For five minutes late Monday night, thanks to what was described as "human error," Ozzie Guillen's blog announced a move that hadn't actually happened yet -- his apparently imminent hiring by the Florida Marlins. Then the blog post, which appears regularly on MLB.com, abruptly vanished, and still hadn't resurfaced Tuesday afternoon, more than 14 hours later.

So what happened? Dinn Mann, the executive vice president and editor-in-chief of MLB Advanced Media, told ESPN.com on Tuesday that a "raw" version of Guillen's post, which was "not intended for public consumption," was mistakenly posted by an employee who simply "hit the wrong button."

Guillen "put something together and submitted it, but it wasn't supposed to go up," Mann said. "It made for an awkward situation, and we feel badly about it."

In the blog post, Guillen thanked the White Sox for the "incredible" years he spent in Chicago but then began explaining his impending move to the Marlins, saying: "The Florida Marlins believe I am the right man for the job to bring another World Series to South Florida."

However, Guillen's contract with the Marlins was still being finalized at the time, and the post wasn't supposed to go public "until something became official," Mann said. So the post was pulled from the site and hasn't been restored. It's expected to reappear when the Marlins announce Guillen's deal, which a source told ESPNChicago.com's Bruce Levine will run through 2015.

On Tuesday afternoon Guillen tweeted: "Weird to be in miami in this time but very happy ready to go".

The Marlins, who move into a new ballpark next spring, plan a big ceremony in conjunction with the final game at their current stadium Wednesday. There's speculation they want to cap the occasion by introducing Guillen as manager.

The buzz began more than a year ago that Guillen might be headed for the Marlins, where he was Jack McKeon's third-base coach with the 2003 World Series champions. McKeon was coy Monday night about the possible hiring of Guillen.

"I like Ozzie," McKeon said. "I think he's a very, very intelligent manager. He was a smart player. He's a good man. I like him."

With a smile, McKeon added, "I'm going to have to like him, right?"

Guillen worked for owner Jeffrey Loria as the Marlins' third base coach in 2002-03. After they won the World Series, Guillen became the White Sox's manager that November.

Guillen's quest for a new deal with the White Sox was denied, so he asked to be released from his contract, and that request was granted. With that, his eight-year run that included a World Series title in 2005 ended.

The White Sox said they retain the right to compensation should Guillen, who had a 678-617 record with the White Sox, accept a managerial position with another major league team for the 2012 season. In order to fulfill that right, the Marlins will send two minor leaguers, including right-handed reliever Jhan Marinez, to Chicago, the source said. MLB.com reported earlier that infielder Osvaldo Martinez is the other player.

Guillen is the only manager in franchise history to lead the White Sox to more than one division or league title. Chicago also made the playoffs under Guillen in 2008 but will finish under .500 this season.
